God knows I'm no Bakshi fan. How anyone ever trusted this hack to even make half a movie about The Lord of the Rings I'll never know!
But one thing he did right was to tap Leonard Rosenman to score his film! Wonderful music full of delightful symphonic surprises, there are even some parts that bring thoughts of Broadway.
I don't know if you have to have some nostalgia from hearing it for the first time backing a truly awful film to like it. All I know is I can enjoy this musical score over and over again while totally disregarding the movie itself.
But it. You won't regret it.
